We booked helicopter flight, bird park, waterfalls and boat tour. The group consisted of 18 people in a small bus. The guide spoke understandable English. The flight took 10 minutes. A lot of money for such a short time but we thought it was worth it! Whether it is absolutely necessary: no! You can visit the waterfalls from different heights, also from a tower and that is wonderful and completely sufficient! The boat tour was great! You get completely wet as they steer the boat into the waterfall! So put on clothes that dry quickly and waterproof your cell phone. Negative: instead of 6-8 hours as advertised, we were on the road for almost 11 hours, since we enjoyed everything, it wasn't a problem for us. But there were people who didn't book all the activities and then had to wait a long time pointlessly. That would have annoyed me immensely. The guide could have communicated a bit better where he waits how everything goes. It was a bit irritating!

Great trip! It is one of the best attractions in Brazil. Buy this trip with Birds park and speedboat for full experience Don’t go to Argentinian side right now as the bridge to Devils throat is destroyed.
